✦ Synopsis

Radiative damping of waves is important in the upper photosphere. It is thus of interest to examine the effect of radiative relaxation on the propagation of waves in an intense magnetic flux tube embedded in a uniform atmosphere. Assuming Newton's law of cooling, it is shown that the radiative energy loss leads to wave damping. Both the 'damping per wavelength' and the 'damping per period' reach maximum value when the sound and radiative timescales are comparable. The stronger the magnetic field, the greater is the damping.
